Summary In this paper a new type of cooling ceiling panel with corrugated surface has been studied experimentally. A heat flux and a heat transfer coefficient for the new type panel were compared with the reference values obtained for a panel of a flat surface. It was shown that increase of the new panel cooling performance results both from increase of its area and from enhancement of natural convection heat transfer. For typical operation conditions, the increase of the new type panel cooling capacity varies from 26 to 55%, in comparison with the reference panel. In addition, the new type panel is more resistant to the risk of dew point and enables the achievement of higher EER values by the heat pump cooperating with it.

“…In addition, if we consider running in cool mode where supply air temperature is limited to dew point, it not only provides us with energy savings compared to other forced air, radiant and convective systems, but allows achieving powers of 75-90 W/m 2 in cooling mode, which other radiant systems cannot reach. Therefore, it has advantages over chilled beams systems [32,33], passive phase change materials systems (PCMs) applied in natural ventilation slabs at night phase [5,34], displacement diffusion or UFAD (underfloor air diffusion) systems or drive of large air flows at low speed systems. The comparison with chilled beam systems is interesting.…”

This research examines the benefits of designing a living space in a basement, as a method of passive temperature control in summer, combined with thermal ceramic panels (TCP) on some walls. These panels incorporate a capillary system of polypropylene tubes which work with cold water. We studied a detached house on the coast of Alicante, where the moderate temperature of the ground tempered interior conditions of comfort using the flow of air from the basement, significantly reducing energy demand and environmental impacts. This reduction was quantified through simulations using the Design Builder tool, having previously monitored the state of the building, on scenarios of a house without a basement, a house with a basement and an all-air system, and a house with a basement and radiant surfaces, using TCP panels on walls. This latter passive system led to a 10.25% reduction in annual energy demand. When we combined it with the two possible air conditioning systems, comfort achieved using the TCP panel system improved by 45.8% compared to the all air system in the living room on the ground floor and by 17% in the basement living room. In addition, annual energy demand and environmental impacts deriving from the use of the installation decreased by 31.8% with the TCP system.
